Ok, so my OPO got into a boot loop. I was running latest SlimKat weekly when suddenly during web browsing session the device rebooted itself and got into a boot loop. Well then I booted into TWRP recovery and wiped all the caches (cache, dalvik) and still no use. Then I did a factory reset and still I got a boot loop. Next thing I installed latest 3 SlimKat weeklys (had them on sd card) with factory resets between them and still the boot loop was there. Then the next few hours I spent installing stock roms from fastboot (22R, 25R, 30O, 33R) and still all I got was the boot loop.
Next morning I booted the device to recovery and did a factory reset and restarted (with 30O rom inside this time). Suddenly the device booted all the way to the Android and I was able to install few apps. Then I installed Whatsapp and launched the app. After the SMS confirmation the device rebooted again and proceeded to a boot loop. I turned the device off and let it settle for about 10 minutes. Then I booted in to the recovery and did the factory reset again and was able to boot all the way to the home screen again! Then after some more app installations came the reboot and boot loop.
Since then I haven't got past the boot animation.
In short terms:
- Was running latest SlimKat weekly
- Reboot and boot loop during normal web browsing
- Did factory reset, didn't help
- Installed stock roms from fastboot (22R, 25R, 30O, 33R), didn't help
What is your opinion? Could there be some hardware issue causing the reboot?

Sometimes device reboots before the actual CM boot animation, sometimes it reboots during the CM boot animation (usually straight after factory reset or flash from fastboot).
I think the hardware is faulty. I got my device to boot with the official AOSP rom and I even managed to install few apps. The device always reboots or completely shuts down when there is something more intensive going on, like downloading file from web site and installing app at the same time. I will try to investigate cpu and battery temperatures after work today.

A customer (I kinda do this for work) brought to me about 8 months ago a MZ604 full stock. I rooted, enabled BigPart, flashed CM11, customer happy. Yesterday he called me because the tablet boots to Android and immediately reboots. Easy, wipe, reflash, done.
Nope. Wiped data, rebooted. All the same. Wiped SYSTEM, I mean, deleting the ROM, all the same. It's like the memory is freezed (like on Windows when you reboot and everything you did in that session resets).
Tried RSD, stock ICS. No avail. RSD reports the flashing was succesful, but everytime I boot I get the same CyanogenMod animation. ROM boots, works for a few secs, and then reboots again.
I HAVE NOT A CLUE. Whatever I do, no change. Noting happens.
Also, when trying to change the recovery via fastboot, it reports it flashed correctly, but the recovery stays the same version.
This isn't as much as a "help!" question because I got the tablet working again (by flashing a stock blob); it's more of an question to try find out if I can prevent this from happening again...
I was just browsing tapatalk when my tablet froze. I rebooted and saw the tablet kept rebooting to the Asus logo. Recovery didn't work (it kept rebooting after the recovery logo would appear) and the the ROM (KatKiss LP v29) wouldn't boot.
Flashing TWRP again with fastboot didn't work. I couldn't flash the ROM again or use my Nandroid... I ended up formatting recovery with fastboot, flashed a stock blob to get it working again, and then restored from there, but it was a pain.
So I'm curious if anyone can guess what may have happened and if there is any way to prevent it from happening again?
I've got quite a peculiar problem with my Nexus 5.
Last night, I left my phone on charge. It was working normally and the software was functional etc. However, once I woke up, the phone was constantly restarting itself, and wouldn't load past the boot animation. I tried to load up fastboot to enter the TWRP recovery, however, the phone froze on the load screen. I should also add that my custom boot animation was replaced by the CyanogenMod mascot.
This problem has never occurred before, and I really haven't got a clue how to fix it. I tried to use WugFresh's NRT to flash a factory image of Android 6, however, the command terminal indicated that each process had failed. This did not restore the phone to its original condition.
I should also point out that I have been running a CM 12.1 nightly, which has been very stable and I have been using this nightly, without major problems (bar the infrequent system UI crashes) for a couple of months. It is obviously rooted and I have a Nandroid backup, which I can't access for aforementioned reasons.
Please could you help me with resurrecting my phone? I would be happy to clarify and elaborate upon any point of information.
Kind regards,
Sami
Have you tried manually wiping cache in fastboot or manually flashing a stock ROM in fastboot mode?

I actually have tried to flash stock Android ROMs, from KitKat to Marshmallow, however, this didn't work as there was a 'write failure' and CyanogenMod wasn't removed. I did erase the cache, but to no luck.
Sounds like the memory module on the phone is defective. I had a Nexus 5 that would constantly re-lock the bootloader after I reboot. I had another N5 where the bootloader remains unlocked and a full wipe in recovery would finish in about 3 seconds which is far too short.
I could only solve both problems by replacing the motherboard.
Ok... slightly frustrated here.
Basic issue: Have flashed CM13 (Nightly 5.17.16) along with the latest Gapps. Upon reboot my phone will go to the Cyanagenmod splash screen, appear to load for several seconds, and then restart. It keeps doing this for at least 10 minutes until I turn it off. I have re-flashed a couple times after reloading the backup but no change.
Process I used: First of all my phone already has Android 6.0.1 firmware installed (not sure if that's an issue). I have TWRP setup as recovery and rooted with su 2.52 (and yes I verified the root prior to flashing). To flash I boot into recovery (obviously), factory reset, install cm13, clear dalvik, and repeat process with gapps. I've done this before with older CM's successfully but for some reason I can't get past the CM splash screen.
Any assistance is appreciated. If I have made a completely stupid error in my process or this exact issue is covered in another thread don't hesitate to point that out!!
Thank you in advance.
You need to be on 5.0 Lollipop. Custom recovery. Rooted. Then flash the ROM after you Wipe in Twrp
So I updated to the latest version of KatKiss, did a wipe first (from Kang TWRP), everything seemed fine the tablet booted and everything was working. I powered off the tablet and went on with my day, when I turned it on again it's in a boot loop. I get the ASUS-logo (at least one time I also got the KatKiss-logo), it tries to boot and it returns to the ASUS-logo. I tried to do a wipe in recovery (Kang TWRP) but it doesn't complete, after around 30 seconds it jumps automatically to the ASUS-logo and tries to boot again.
Any solution greatly appreciated.

Please try to get into "Fastboot Protocol" by holding the button volume down at the time before the boot loop starts newly again. Three icons will appear. The first one, RCK; is blinking. Press volume up and your TWRP should start. Hopefully you have Kang TWRP. If so you may install rom, gapps and SuperSU again by following exactly the install instruction by Timduru here: https://forum.xda-developers.com/tra...t/rom-t3453702.
(Don't forget to do "Format Data" through Kang TWRP as first of all. It takes up to one hour. Be patient and let it run.)
I'm sorry, but if you are really not able to boot into either fastboot or recovery the tablet is bricked for good!
Thank you for advice.
The tablet is up and running again. I wasen't able to boot into Kang TWRP, but I was able to use fastboot. I ran a lot of erase commands that I found in a guide, erase boot, erase recovery, erase userdata etc., afterwards I flashed stock rom. It still wouldn't boot, but I installed Kang TWRP with fastboot and I was able to use TWRP again so I was able to flash a custom rom and it booted up again.

Congratulations! You did a good job. Seems as if you did the well known "Buster99 Solution" successfully in order to get back on stock rom. Keep it in your mind for ever. It may be also helpfully in other cases of trouble.
odd loop.

Randomly my tablet started doing the boot loop. It would show the Asus Logo, then the Kattkiss logo and it will go to a screen saying optimizing apps. It would go through and optimize all 1-75 then reboot and start the process again. I unhooked the dock and allowed it to do this until the battery was completely dead. Next day same thing. This tablet has been unchanged OS wise for about 2 years. only used for youtube videos. Super odd that it randomly broke.
It does have a good TWRP version installed v2.8.7.0. So I tried flashing the 7.1 rom, su, gapps and wiped cache/dalvik. Did not correct it. So then did factory reset. Still no go. Now i am doing a full wipe / format. After format i will reinstall katkiss 7.1, su, and gapps. Hopefully i get back to normal after that.
Absolutely no idea what spurred this or what caused the break. Has been completely normal for a very long time. Weird.
Anybody else see anything like this?

I don't think so. In order to get this Rom installed on your devise you need Kang TWRP as advised by @timduru https://forum.xda-developers.com/transformer-tf300t/development/recovery-twrp-t3046479.
